“Blue” Is The Sixth Track On The Band’s Self-Titled Third Studio Album "The Neighbourhood". The Track Boasts A Groovy Hip-Hop Style Beat Reminiscent Of Their 2014 Mixtape. The Song Details The Feeling Of Something Building Up But Never Reaching An End Point Hoping On Something And Being Let Down. The Lyrics Are Littered With Euphemisms Using Sexual Frustration As A Metaphor For This.
